Super flower is reliable brand, most of the evga psu also manufactured by super flower. However i suggest u may consider buy those brand or model which have the longest warranty period, eg evga supernova g3 750w & above is having 10years warranty, same for certain model for corsair like HX & ax series.

Hi all, i RMA my Corsair AX1200i PSU 3 months ago, this morning i received a call from Convergent Distribution that my PSU is ready for collection, after further checking was told it is a refurbished PSU, is it normal Corsair will RMA refurbished PSU?

I know there is TnC there but i'm not sure it is common or not, based on my previous experience, i RMA my previous unit same model few years ago, they returned with a brand new sealed unit.

A 1000w psu doesn’t mean the PC will always consume 1000 watts. It simply means the power supply can provide up to 1000 watts if needed. The actual power consumption depends on the hardware components and how much power they draw during use. For instance, a GPU like the RTX 5090 might use up to 600 watts under full load, but it will use much less when idle or under light use. So your system’s total power draw could vary a lot depending on what you’re doing.

If you're worried about your TNB bill, then the RTX 5090 probably isn't for you. I did a general test by undervolting my RTX 5090 (0.875V @ 2.6GHz) and running it with my 9950X3D using a PBO setting of -30. The purpose of the test is to see if I need to upgrade my 1000W PSU to a higher wattage. Using 3DMark for the test, the system's maximum power draw from the wall was around 700W.
